I have a 98 k1500, all stock besides the 35’s, stage 1 trans, gearing change ( I swapped the 10 bolt for a 14 bolt and it has 3.73s) and I cut the front lip off the throttle plate, and muffler delete. I do some towing but not all the time it’s mainly a daily. I would like to be able to change tunes on the fly via maps ( I believe that’s how it works, maps are like different presaved tunes example one for economy, one for towing, one for more hp ect) would I be better off with a hand held or sending my pcm off to a tuner such as blackbear? And I need my Speedo calibrated too
